The obstruction of the urinary flow can take place inside the renal tubules as well as in any other segment of the urinary tract renal pelvis, ureter, bladder and urethra. Obstructive uropathy and benign uropatiw hyperplasia.
Obstructive uropathy is a mechanism of renal insufficiency, which since it is relatively simple to solve, should always be taken into consideration as one of the differential diagnosis of renal failure. Intratubular hydrodynamic forces influence tubulointerstitial fibrosis in the kidney. Decrease of ultrasound estimated bladder weight during tamsulosin treatment in patients benign prostatic enlargement.
Usually glomerular hydrostatic pressure is largely predominant, on whom the net ultrafiltration pressure depends almost completely.
This div only appears when the trigger link is hovered over. Regarding the urinary obstruction mechanisms, it is possible to divide them into those which are intra-renal intratubular and those which are extra-renal. You can also find results for a single author or contributor. Curr Opin Nephrol Hypertens ; Comment of the reviewer Jesus Garrido MD.
The role of bone morphogenic protein-7 and hepatocyte growth ifsiopatologia. Factors determining the amount of residual urine in men with bladder outlet obstruction: A later resolution can mean partial or nule recovery, depending on the evolution time of the obstruction, the age of the patient and the degree of damage to the renal function previous to the obstruction.
Search within a content type, and even narrow to one or more resources.
Klahr Onstructiva, Morrissey J.: It is also stated that the damaged tubules release a chemotactic substance which would attract monocytes and macrophagues, which would infiltrate the renal parenchyma, damaging it by means of the local release of proteases and free radicals.
Servicio de ayuda de la revista. Data obtained from tests performed in animal models and information obtained from the evolution of clinical cases, suggest that the resolution of a complete obstruction before obstrudtiva weeks after it has settled can achieve a total recovery of the glomerular filtration.
Role of angiotensin II in chronic ureteral obstruction. About MyAccess If your institution subscribes to this resource, and you don’t have a MyAccess Profile, please contact your library’s reference desk for information on how to gain access to this resource from off-campus. On the other hand, such pressure is transmitted to the tubular sectors proximal to the obstruction causing a reduction of uropattia glomerular filtration since it counteracts to the glomerular filtration net pressure.
Obstruction-induced alterations within the urinary bladder and their role in the pathophysiology of lower urinary tract symptomatology.
Hospital Italiano de Buenos Aires. Rohatgi R, Flores D: Nephron Exp Nephrol ; The effect of bladder outlet obstruction treatment on ultrasound-determined bladder wall thickness.
In conclusion, since obstructive nephropathy is a potentially reversible cause of renal dysfunction, it should always be taken into account among the differential diagnosis of renal failure inducing mechanisms.
The latter can be subdivided into those which have intrinsic and extrinsic causes to the urinary tract Cystometric parameters and fisiopztologia activity of signaling proteins in association with the compensation or decompensation of bladder function in an animal experimental model of partial bladder outlet obstruction. Nevertheless, if the obstruction is sustained in time, it leads to intrarenal vasoconstriction with the subsequent reduction in the glomerular blood flow.

J Clin Invest ; Arch Ital Urol Androl. Independently of the place where the urinary obstruction happens, and from this moment, a series of events start to happen, which if they are not corrected can lead, in time, to irreversible renal damage and tubular atrophy.
